Most domain and web hosting plans expire when no one pays to renew them.
One thing you could do is put your work under a free license. That would allow people to copy it which should make sure that your work will be preserved by others.
In the vast majority of countries, everything written down is automatically copyrighted by default and if you want to release it into the public domain or under a free license you have to make it explicit.
To my understanding this means historically a western communist who supported the USSR’s interventions (with tanks, hence the name) in Eastern European countries (Hungary, Czechoslovakia, maybe also East Germany) when the Warsaw Pact was a thing. More broadly someone who thinks the Soviet Union was a good regime.
In the 2000s (very young at the time) I sometimes thought about how awesome it would be if we had devices where we could go on the Internet from everywhere.
I do not want the world back where people could only look things up on the Internet from home or work or where there is a desktop computer.
Yes. But we have all gotten pretty used to things on the Internet not costing money. If they start costing money, many people will either not want to or be able to use them.
Freely licensed works will be preserved a lot better because there will be more copies of them.
Likewise the fediverse is a step in that direction: this message will be federated to hundreds of servers so is more likely to survive longer than if I posted it to reddit.
When public transportation was first introduced in most places, it was run by private companies for profit. This changed mostly because it wasn’t profitable to compete with cars when those became popular.
Of course there still are private companies running public transport: long distance buses and trains in many places, and commercial aviation is really also a form of public transportation.
So there is nothing novel about buses being run by private companies for profit.
